Success Rate, Type of Delivery, and Neonatal Outcomes in Pregnancies Achieved Through Embryo Cryotransfer

Background: The use of assisted reproductive technologies, particularly frozen embryo transfer (FET), has become increasingly prevalent as a means to address infertility. This study aimed to evaluate the success rate, delivery type, and neonatal outcomes following FET in hormonally prepared cycles within a single tertiary center. Methods: We conducted a retrospective analysis of 275 women who underwent FET. Patient age, infertility factors, pregnancy outcomes, delivery type, and neonatal data—including birth weight and Apgar scores—were analyzed descriptively. Results: Pregnancy was achieved in 28.0% of FET cycles, with a singleton rate of 97.3%. Term births represented 70.7% of pregnancies, and cesarean delivery occurred in 29.3% of cases. Neonatal outcomes were favorable: in singleton pregnancies, 89.3% of newborns had a birth weight between 2,500–4,000g, and all neonates exhibited Apgar scores ≥7 at both one and five minutes. Multiple pregnancies were uncommon (2.7%) but associated with a higher frequency of low birth weight (<2,500g). Conclusion: FET is a safe and effective strategy for achieving pregnancy, with high rates of singleton gestations and positive perinatal outcomes. However, the retrospective, single-center design and limited sample size constrain the generalizability and the ability to assess rare outcomes.
